    The SY83088J is a high efficiency synchronous buck converter operating over a wide input voltage range of 4V to 24V and capable of delivering up to 8A current. It integrates low RDS(ON) top and bottom MOSFETs to minimize the conduction loss. It operates at a pseudo-constant frequency of 600kHz, to enable the use of small size inductor and capacitors. The SY83088J also provides a fixed 3.3V LDO with 100mA current capability, which can be used to power the external peripheries. The 3.3V LDO can switch to BYP input to reduce power loss.
